Potatoes are very sensitive to the temperature of storage environment, the temperature is too low easy to frostbite, loss of edible value; temperature is too high to germinate to produce toxins, the temperature of the potato inside starch and sugar conversion process will have a great impact.

The experiment proved that under 0 ℃ condition, the activity of the starch hydrolase increased, the starch hydrolysis was faster and the respiration intensity was reduced, so the suitable storage temperature of potatoes was 3~10℃, and the storage temperature of the potatoes was different depending on the use of the potato.

The relative humidity of the storage environment has an effect on the storage quality of the potatoes, the moisture evaporates quickly when the air is dry, the potato skin wrinkles, the air is moist and easy to sweat, causing the potato to rot, and its storage suitable relative humidity is 95~98%.
